In this episode, Mr. Krabs creates a "promotion" to the Krusty Krab by selling Regular, Large and Viking Sized Drinks (which really are all the same size) in a bid to save the restaurant money, yet at the same time, to fool the customers into paying more money for the same size drink. He also states that whoever purchases a Viking Sized cup tries on a cardboard helmet (that he found in his attic) which is also a gimmick to obtain money. This gets SpongeBob interested in Vikings. Squidward then teaches him about Vikings, though nothing he said was true. Then SpongeBob sends a letter to the Vikings.
Meanwhile, at the post office, a garbageman (who is a Viking) notices it and delivers the letter to the Viking Chief. He then sends his men to the Krusty Krab to teach them about the Vikings (which is redecorating, appropriating, and liberating) and they kidnap SpongeBob and Squidward. Then, the they introduce themselves as Gordon and a bunch of Olafs. SpongeBob then asks what they do for fun (which is just throwing a shield), then one says they like to sing songs even though they actually not. The Vikings make SpongeBob the head chef, and Squidward the bathroom attendant. Soon afterward, Squidward complains about the poor lifestyle, which causes him to be tied to a catapult. Soon, the Vikings discover that they have hit a rock and that their boat will leak, which gives SpongeBob an idea. He then plugs up the boat with his porous appearance, and saves the Vikings.
